光传送网(OTN)的性能监测技术

Optical Transport Network Performance Monitor Techniques

本文系统地介绍了目前光传送网性能监测的各种技术 ,包括BIP字节法 ,准误码率监测QBM法、抽样统计法和各种光信噪比监测法。文中给出了这些方法的基本原理和实验结果并比较了它们各自的优缺点。最后 ,作者对光传送网的性能监测问题提出了自己的看法。

In this paper, we introduce several performance monitoring techniques for optical transport networks, including the BIP technology, the quasi-bit error monitoring technology, the sampling statistical method and the optical signal to noise ratio monitoring technology. We describe the principles, the experiment results, the advantages and disadvantages of these techniques. At last, we give our opinion on this topic.
